Several downtown roadways will be closed Saturday night as thousands of cyclists ride through town in the moonlight.

The 21st annual InnovAge Moonlight Classic will start at 8:30 p.m. and end at 2 a.m. Saturday. The 10-mile course starts and ends at the Colorado State Capital.

The course will take riders through the business district, Lower Downtown, Congress Park, the Cherry Creek shopping district and more, and many of the roads in those areas will be closed to vehicular traffic, according to the Moonlight Classic website.

Only certain lanes will close on Speer Boulevard, Lawrence Street, 17th Street and Broadway, allowing traffic to flow through those areas.

Online registration for the event is closed, but cyclists can sign up starting at 8:30 p.m. at the registration tent on Broadway between 14th Avenue and Colfax Avenue.

Registration is $50 for adults and $40 for children 17 and younger and seniors.
